Abstract

A touch panel including: a substrate; first conductive patterns separately disposed on the substrate with a preset distance therebetween; second conductive patterns formed thereon to separately intersect the first conductive patterns with a preset distance therebetween; a second connecting member configured to connect adjacent second conductive patterns to each other; an insulating pattern configured to cover a preselected region of the second connecting member; and a first connecting member disposed on the insulating pattern to connect adjacent first conductive patterns to each other. The first conductive patterns and the second conductive pattern portion are flexible.

First claim

What is claimed is:

1. A touch panel comprising:
a substrate;
rows of first conductive patterns disposed on the substrate in a first direction and spaced apart by a preset distance, each first conductive pattern being separately formed;
columns of second conductive patterns disposed on the substrate in a second direction so as to separately intersect the rows of the first conductive patterns, the columns being spaced apart by a preset distance;
a second connecting member connecting adjacent second conductive patterns;
an insulating pattern covering a preselected region of the second connecting member; and
a first connecting member disposed on the insulating pattern connecting adjacent first conductive patterns; and
an auxiliary connecting member having an edge overlapping an edge of the first connecting member,
wherein the first conductive patterns and the second conductive patterns are flexible.

2. The touch panel of claim 1 , wherein the first connecting member comprises a transparent conductive oxide (TCO).

3. A touch panel comprising:
a substrate;
rows of first conductive patterns disposed on the substrate in a first direction and spaced apart by a preset distance, each first conductive pattern being separately formed;
columns of second conductive patterns disposed on the substrate in a second direction so as to separately intersect the rows of the first conductive patterns, the columns being spaced apart by a preset distance;
a second connecting member connecting adjacent second conductive patterns;
an insulating pattern covering a preselected region of the second connecting member;
a first connecting member disposed on the insulating pattern connecting adjacent first conductive patterns; and
an auxiliary connecting member having an edge overlapping an edge of the first connecting member,
wherein:
the first conductive patterns and the second conductive patterns are flexible;
the first conductive patterns, the second conductive patterns, and the second connecting member comprise silver nanowires (AgNW);
wherein the substrate comprises a polymer resin layer; and
the first conductive patterns are electrically connected to each other by the first connecting member and the second conductive patterns are connected to each other by the second connecting member.

4. The touch panel of claim 3 , wherein the first connecting member comprises a transparent conductive oxide (TCO).
